Solution

1. Preparation

Gather necessary tools:
- Clean, lint-free cloth
- Funnel (if adding fluid)
Ensure the vehicle is parked on a level surface and the engine is warmed up.

2. Checking Fluid Level

Locate the transmission dipstick, which is typically marked with a bright handle.
Remove the dipstick, wipe it clean with a cloth, and reinsert it fully.
Pull the dipstick out again and check the fluid level against the markings on the dipstick. The level should be within the "HOT" range if the engine is warmed up.

3. Adding Transmission Fluid (if necessary)

If the fluid level is low, use a funnel to add the appropriate type of transmission fluid (refer to the owner's manual for the correct fluid specification).
Add fluid in small increments, checking the level frequently to avoid overfilling.

4. Finalizing

Once the fluid level is correct, securely replace the dipstick.
Close the hood of the vehicle.
